Question

The glycosidic bonds in DNA and RNA
A.connect the sugar to the base
B. can be hydrolyzed by OH- ion
C. stabilize Watson-Crick H-bonds
D. are free to rotate over about 180°

Answer 1

A- Connect sugar to the base,

Explanation:

• Sugar and nitrogen base form a glycosidic link in the DNA molecule.
• The nitrogen-carbon linkage between the 9' nitrogen of purine bases or the 1' nitrogen of pyrimidine bases and the 1' carbon of the sugar group forms the glycosidic bond.
• Deoxyribose is a sugar found in DNA.
• A nucleoside, on the other hand, is a molecule or polymer made up entirely of sugar and a nitrogenous base.
• Bonding is required to bind these sugar molecules, nitrogenous bases, and phosphate groups together.
• The glycosidic bond, also known as N-glycosidic linkage, is the bond that exists between sugar and nitrogen base.

Answer 2

Answer:

A) The glycosidic bonds in DNA and RNA connect the sugar to the base.

Explanation:

• The glycosidic bond, also known as N-glycosidic linkage, is the bond that exists between sugar and nitrogen base.
• A phosphodiester bond is the link that binds or connects the phosphate group to the sugar molecule.
• The nucleoside is formed when the nitrogen base is linked to the sugar molecule in DNA and RNA.
